Summary: Deep Zoom "contest" proposed
Keywords: mandelbrot deepzoom  fractint
X-Newsreader: TIN [version 1.2 PL2]
 
Jay Hill has done some good work investigating deep zooms of the Mandelbrot.
His deep zoom program was one of the inspirations for adding arbitrary
precision to Fractint. It is relatively easy to convert back and forth
between input for his program and input for Fractint. Just take the 
reciprocol of the magnification (used by Fractint) to get the side (used 
by deepzoom) or vice versa. Both programs use the center.
 
I'd like to propose an informal "deep zooming" contest to challenge folks 
to come up with the deepest zoom that is an interesting image and not in 
one of the "vortices of self-similarity" that are fruitless to zoom into.
 
For starters, here is a Jay Hill example converted to Fractint's PAR form.
It should be relatively easy for any deep-zoom-capable program to
calculate this.
